# Interactive regex selection (`s` / `S`) and the comment toggle, on a real
# file pane. hxdiff pins what they DO against a real helix, but it is headless,
# so this is the half it cannot see: the prompt living in the TAG rather than a
# popup, the matches lighting up under a pattern as it is typed, Esc putting
# back what was there, and Ctrl-c using the token this file's EXTENSION asks
# for — `//`, where a buffer with no language would get `#`.
file m.zig const one = 1;\nconst two = 2;\nconst three = 3;\n
# wide on purpose: the whole point of this script is a tag long enough to hold
# the marker AND the pattern, and a narrow pane simply truncates it away
